From 311baaf93c4b9e6a339722006d1a7c33e4283c0c Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 4 Oct 2019 15:01:30 -0300 Subject: [PATCH] perf trace: Enclose all events argument lists with () MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit So that they look a bit like normal strace-like syscall enter+exit lines. They will look even more when we switch from using libtraceevent's tep_print_event() routine in favour of using all the perf beautifiers used by the strace-like syscall enter+exit lines.
